Abstract

fetched live from OpenAlex

In this paper, we propose two improvements to modeling other agents based on Observed Situation-Action Pairs and the Nearest Neighbor Rule --reevaluative stereotyping with switching and compactification of observations through kd-tree structuring and the Pseudo-Approximate Nearest Neighbor search. On the one hand, tentative stereotype models allow for good predictions of a modeled agent's behavior even after few observations. Periodic reevaluations of the chosen stereotype and of the stereotyping process itself, in addition to the potential for switching between different stereotypes or to the observation based model aids in dealing with very similar but not identical stereotypes and agents that do not conform to any stereotype. On the other hand, reducing comparisons for the Nearest Neighbor Rule by observation compactification keeps the application of the model efficient even after many observations have been made. Our experiments show that tentative stereotyping significantly improves cases in which the original method performs badly and that reevaluations and switching fortify stereotyping against the potential risk of using an incorrect stereotype. For compactification, our experiments show that using the kd-tree for compactifying observations and the Pseudo-Approximate Nearest Neighbor search for retrieving a Nearest Neighbor improves modeling efficiency when observations are abundant, but is sometimes coupled with a loss of accuracy.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
